An Israeli attack in northern Gaza has killed the three sons of Hamas leader Ismail Haniyeh.
In an interview with Al Jazeera Arabic, Haniyeh confirmed the killing of his children Hazem, Amir and Mohammad along with a number of his grandchildren this Wednesday.
He said they were targeted while visiting relatives for Eid in the Shati refugee camp.
"Through the blood of the martyrs and the pain of the injured, we create hope, we create the future, we create independence and freedom for our people and our nation," Haniyeh said.
The political leader of Hamas, which is based in the state of Qatar, condemned what he described as Israel's brutality in Gaza and stressed that Palestinian leaders will not back down if their families and homes are targeted.
"There is no doubt that this criminal enemy is driven by the spirit of revenge and the spirit of killing and bloodshed and does not respect any standards or laws," Haniyeh said.
"We have seen him trample everything on the land of Gaza. There is a war of ethnic cleansing and genocide. There is massive displacement," he added.
